Question

A rectangular floor is 21 feet long and 9 feet wide. what is the area of the floor in square yards

Answer 1

Answer: 21

Step-by-step explanation: A = 9 *21

A = 189 square feet

Dividing 189 by 9, you get 21 square yards.

Answer 2

The question asked for the area in square *yards*, so we have to be careful to convert the dimensions of the floor to yards before measuring the area. There are 3 feet in 1 yard, so 21 ft = 21/3 = 7 yd, and 9 ft = 9/3 = 3 yd.

To the area of any rectangle is simply the product of its length and width; given a length of 7 yd and a width of 3 yd, the area of this floor is 7 x 3 = 21 sq. yd
